以湖南主要烟区植烟土壤为研究对象，采用Warning淹水培养法，对植烟土壤进行矿化培养试验，深入研究不同烟区土壤有机氮矿化特性。结果表明，湖南省植烟土壤有机氮矿化速率均表现为前期较快，后期缓慢。湘南、湘中、湘西植烟土壤有机氮矿化积累量、矿化速率、矿化势相差较大，且均表现为“湘中>湘南>湘西”。矿化氮与全氮、有机质线性回归结果显示，与矿化氮含量密切相关的依次为活性有机碳>全氮>有机质>腐殖质碳。总体表明，活性有机碳与矿化氮量密切相关，是矿化的主体。

Soil mineralization culture experiments by Warning’s method were conducted to investigate the mineralization characteristics of soil organic N in tobacco field by using soils from several typical tobacco fields in Hunan province. The results showed that, for all of the soil samples, the mineralization rate of soil organic N was fast in early stage and slow in late stage. Mineralized nitrogen accumulation, mineralization rate, and mineralization potential were different among the three typical tobacco fields, e.g., middle Hunan>southern Hunan>western Hunan. The regression analysis showed that active organic carbon, total nitrogen, total organic matter, and soil humus, from strong to weak, were most influential to soil mineralization nitrogen content. Overall, active organic carbon had the closest relationship with mineralized nitrogen accumulation and was the major origin of the mineralization .
